INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air
temperature will be between 40°F and 100°F. Intermittent
operation at ambient temperatures up to 113°F will not
damage the dryer but may result in a higher dew point
ordryershutdownduetohighrefrigerantdischarge
pressure (see Field Service Guide).
Do not operate air-cooled dryers at ambient air
temperatures below 40°F. Such operation may result in
lowsuctionpressure,causingfreeze-up.
Callyourlocaldistributorifprolongedoperationat
ambient temperatures above 100°F or below 40°F is
unavoidable.
Location and Clearance
Mount the dryer on a level base. Install the dryer in
aclean,well-ventilatedareatoreducefoulingofthe
condenser coils with dirt and dust.
Wall Mounting - Dryer may be wall mounted by using
